There are two randomly placed Lions of Fo out of 20 possible locations. Before being made available, their possible locations are represented in-game by swirling blue dots on the ground - these do not serve any other purpose. The Lions can only be found after completing the mission Salt in the Wound. Finding both is required for 100% completion. In the Nintendo DS and PSP versions, finding them unlocks the Xin Shan missions downloadable from the Rockstar Social Club, but the missions are not required for 100% completion. Due to a lack of Social Club compatibility, the Apple iPhone mission omits the Lions and makes the Xin missions automatically available. Unlike most collectibles in GTA Chinatown Wars, the locations of the Lions are not shown in the PDA.

Trivia

Once you've found the first statue, the second statue shouldn't be far away from the first one.
